Embodiment 1

[0013] Example 1, such as figure 1 As shown, the intercom center system executes the self-inspection of the intercom panel at the set time point. For example, the detection time can be set at 4-6 o'clock in the morning, when the environment is relatively quiet, the external influence is small, and the equipment is not in use. When the system is installed for the first time, the template audio confirmation method can be completed by the following method. Select a continuous and uninterrupted voice broadcast such as "Welcome to XXXX self-service bank" as the original audio file; when the system is installed for the first time, ensure that the system It is normal, there is no hardware problem, and then in a quiet environment, use the speaker (speaker) on the panel to broadcast the audio file; then collect it through the microphone on the panel and upload it to the central server to save it as a template audio file; in order to give the original The actual system hardware noise is...

Abstract

The invention belongs to the technical field of electronic communication and particularly relates to an intercom panel self-test method. An audio signal played by a loudspeaker under the normal condition is collected by a microphone and uploaded to an intercom center as a template audio; an audio signal of the loudspeaker played at the detection time is collected and uploaded to the intercom center as a collected audio through the microphone; the template audio and the collected audio are converted by the intercom center from the time domain to the frequency domain, and the frequency domain energy spectrum is respectively calculated; a correlation coefficient of the frequency spectrums of the collected audio and the template audio is calculated through the Pearson correlation coefficient calculation formula; when the correlation coefficient is greater than or equal to a set threshold, an intercom panel is determined to be normal; when the correlation coefficient is less than the set threshold, the intercom panel is determined to be abnormal. The method is advantaged in that a fault problem of the equipment having only a slight fault can be detected, the detection result is more sensitive and accurate, operation is simple, the equipment fault is effectively eliminated, and operation of the intercom panel is more stable.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and in particular relates to a self-checking method of an intercom panel. Background technique [0002] The detection of the intercom panel in the prior art is realized by the hardware self-test function of the panel. This method can only play a role when a certain hardware component is completely damaged and cannot work. When some components are abnormal, if When the microphone or speaker on the panel has a slight fault, the device is still working, but the self-test function of the hardware cannot detect it, which seriously affects the quality of the conversation, and even affects the call at an important moment. The existing technology is unable to solve this problem. detected, and there is no good solution. Contents of the invention [0003] The invention provides a method for self-inspection of the intercom panel, which solves the drawback that the intercom panel detectio...
